Paste both complete versions
Each prompt is evaluated independently using the same text checks and score caps.
PROMPT QUALITY COMPARISON
Prompt Version Comparator
Compare two coding prompts with the same transparent heuristics for specificity, constraints, examples, acceptance checks, and ambiguity risk.

How it works
Compare six signals
Length-based specificity, constraints, format, verification, and examples add points while vague language removes them.
Review the winning content
Carry forward the clearer requirements, but manually verify technical truth and avoid choosing a version solely by score.

Frequently asked questions
Does the higher score guarantee a better model response?
No. It indicates stronger visible prompt structure under these heuristics. Model, repository context, task difficulty, and technical correctness still affect results.
Why does prompt length add points?
Only the first 120 words contribute, as a rough specificity signal. Extra length beyond that does not increase this part of the score.
Can I compare prompts for different tasks?
You can, but the result is less useful. Compare two versions with the same intended outcome, context, model, and constraints.

GitHub Copilot and Cursor can help draft or act on coding prompts. MVPHub compares two pasted versions with one disclosed heuristic and does not run either prompt against a model.
